Please merge nomis fix for this warning, same fix has to be applied to ESP32 as I actually had same warning on ESP32.

Using v2.3.5 I ran into the same warning with the ESP32. It is easy to reproduce, add the Warnings: All flag to the Arduino IDE.

Please merge this branch as thoose viabels are not used. If someone has this problem open OneWire.cpp in your documents and delete "volatile IO_REG_TYPE *reg IO_REG_BASE_ATTR = baseReg;" from the functions Readbit WriteBit and reset and your program should compile and work
